According to a study carried out by two master’s students at Linköping University, large amounts of carbon dioxide equivalents taken up by plants on land are returned to the atmosphere from aquatic environments.

Researchers are developing a new kind of geothermal power plant that will lock away unwanted carbon dioxide (CO2) underground – and use it as a tool to boost electric power generation by at least 10 times compared to existing geothermal energy approaches.

Even if carbon dioxide emissions came to a sudden halt, the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years, according to Princeton University-led research published in the journal Nature Climate Change. The study suggests that it might take a lot less carbon than previously thought to reach the global temperature scientists deem unsafe.

Scientists have long suspected that a flourishing of green foliage around the globe, observed since the early 1980s in satellite data, springs at least in part from the increasing concentration of carbon dioxide in Earth’s atmosphere.

Chlorofluorocarbons (CFCs) are to blame for global warming since the 1970s and not carbon dioxide, claims new research from the University of Waterloo recently published in the International Journal of Modern Physics B.

Earth's repeated flip-flopping between greenhouse and icehouse states over the past 500 million years may have been caused by volcanoes at particular spots where enormous amounts of carbon dioxide are released into the atmosphere.

An international team of researchers studying data beamed back by NASA's Mars Reconnaissance Orbiter have observed seasonal changes on far-northern sand dunes on the Red Planet caused by warming of a winter blanket of frozen carbon dioxide.

The permafrost covering almost a quarter of the northern hemisphere contains twice as much carbon as is currently in the atmosphere, and could significantly amplify global warming should thawing accelerate as expected.
